Turn ‘What If?’ Into Certainty

Running a successful manufacturing business means managing your inventory and stock levels and projecting what you need for the future wisely. Wherefour’s unique “What If?” function lets you enter a series of products or formulas with production multipliers and instantly know if you have enough on hand to meet production. If not, Wherefour tells you what you need to order to do so. You’ll even get the estimated cost, based on your current inventory costs.

Enterprise-grade MRP With One Click

To plan upcoming inventory needs, Wherefour helps you create a full material requirements plan (MRP) quickly and easily. A materials requirements plan considers all the data in your account, such as future sales, stock on hand, open purchase orders, production and supplier lead times, and customer orders to determine what you may run out of and when you need to reorder it.
